Lot of 60 genuine TDK CGJ3E2X7R1C104K080AA high-reliability multilayer ceramic chip capacitors supplied from original Mouser Electronics distributor-labeled inventory.

These capacitors provide 0.1uF / 100nF capacitance with ±10% tolerance, a 16V DC rating, and X7R dielectric in the common 0603 EIA / 1608 metric surface-mount package.

Unlike an ordinary general-purpose 0.1uF ceramic capacitor, the CGJ3E2X7R1C104K080AA belongs to TDK's CGJ high-reliability MLCC family and carries AEC-Q200 qualification. This makes the exact component particularly relevant to automotive, industrial, communications, control, and other equipment where qualification and reliability requirements can matter in addition to nominal capacitance.

Key manufacturer specifications include:

0.1uF / 100nF capacitance
100,000pF nominal capacitance
±10% tolerance
16V DC rated voltage
X7R temperature characteristic
±15% X7R temperature-capacitance characteristic
0603 EIA / 1608 metric package
Approximately 1.60 mm x 0.80 mm body dimensions
Approximately 0.80 mm nominal thickness
-55°C to +125°C operating temperature range
5% maximum dissipation factor
1000 megohms minimum insulation resistance
AEC-Q200 qualified
High-reliability grade
Multilayer ceramic construction
Non-polarized
Surface-mount mounting
Wave and reflow solder compatible
Lead-free / RoHS compliant
Paper carrier-tape packaging

X7R ceramic dielectric is widely used where designers require good capacitance density together with substantially better temperature stability than lower-grade Class 2 dielectrics. The X7R designation specifies operation from -55°C through +125°C with capacitance change held within approximately ±15% over that specified temperature range.

The 0.1uF / 100nF value has long been one of the most important decoupling and bypass values in electronics. These capacitors may be positioned close to IC supply pins, communications transceivers, microcontrollers, regulators, analog devices, automotive interface circuits, and other active components to provide a local charge reservoir and a low-impedance path for unwanted high-frequency supply noise.

The 0603 footprint provides a useful balance between compact PCB area and practical manufacturing. At approximately 1.6 mm x 0.8 mm, these capacitors are small enough for high-density assemblies yet are still encountered extensively in repairable industrial, automotive, communications, and test-equipment circuit boards.

LIFECYCLE STATUS: OBSOLETE

TDK CGJ3E2X7R1C104K080AA is officially classified as obsolete.

TDK's current product record identifies the exact manufacturer part number as OBSOLETE. Mouser also identifies the component as obsolete and provides a Product Discontinuance Notification dated June 10, 2022.

This means new production of the original CGJ component has ended and remaining inventory represents legacy distributor stock, surplus inventory, or previously purchased manufacturing stock.

Digi-Key identifies TDK CGA3E2X7R1E104K080AA as the manufacturer-recommended replacement. The CGA device retains the 0.1uF ±10%, X7R, 0603 / 1608 metric construction and AEC-Q200 qualification while increasing the rated voltage from the original CGJ part's 16V to 25V.

Although TDK's CGA replacement is a strong modern replacement candidate, technicians servicing legacy equipment should verify circuit requirements, qualification requirements, dimensions, DC-bias behavior, and manufacturer documentation before substitution.

HISTORICAL BACKGROUND:

TDK was founded in Japan in 1935 and became one of the world's major manufacturers of magnetic materials and passive electronic components. The company later developed extensive capacitor, inductor, sensor, ferrite, transformer, power-component, and electronic-material product families used throughout consumer, industrial, communications, automotive, aerospace-support, and test applications.

Multilayer ceramic capacitors became increasingly important as electronic manufacturing shifted from through-hole circuit boards toward compact automated surface-mount assembly.

An MLCC contains many alternating layers of ceramic dielectric and internal electrodes within a single monolithic body. This multilayer construction allows useful capacitance values to be produced in very small physical packages while providing extremely low series inductance compared with many traditional leaded capacitors.

The 0.1uF ceramic capacitor became one of the standard building blocks of modern digital electronics. As integrated circuits became faster, designers increasingly placed small ceramic capacitors directly adjacent to IC power pins to suppress switching transients and prevent high-frequency noise from propagating throughout the power distribution network.

TDK's CGJ family extended this familiar MLCC technology into higher-reliability applications. Rather than serving solely as a commercial-grade bypass capacitor, CGJ devices were developed around additional reliability requirements and AEC-Q200 qualification.

AEC-Q200 is a widely recognized qualification framework for passive components used in automotive applications. Components qualified to the standard undergo environmental and electrical-stress testing intended to demonstrate suitability for demanding vehicle electronics environments.

This exact CGJ3E2X7R1C104K080AA also has documented engineering use in automotive communications hardware.

Texas Instruments specifies CGJ3E2X7R1C104K080AA in the bill of materials for its TCAN1463-Q1 Evaluation Module with SIC network. The exact TDK capacitor is used at reference designators C9, C10, C14, and C17 and is described by Texas Instruments as a 0.1uF, 16V, ±10%, X7R, AEC-Q200 Grade 1, 0603 ceramic capacitor.

That documented use is significant because the TCAN1463-Q1 platform is associated with automotive CAN communication circuitry, demonstrating the type of high-reliability electronics for which this TDK CGJ component was selected.

As component families evolve, manufacturers periodically consolidate older lines into newer standardized families. TDK ultimately discontinued CGJ3E2X7R1C104K080AA and transitioned replacement demand toward its CGA automotive-grade capacitor family.

The RF Boneyard inventory therefore represents genuine unused legacy stock of an obsolete AEC-Q200 TDK MLCC rather than merely a generic current-production 0.1uF capacitor.
